ormaaj 1358919410 learn ''=~'' is a binary operator used within Bash or ksh93 test expression compound commands ''[['' to perform pattern matching with extended regular expressions (ERE). Regex grouping may be done with the BASH_REMATCH array (bash) or .sh.match (ksh93) variables. Older buggy versions of Bash require storing the regex in a variable. ksh93 can use ERE elsewhere using the ~(E) pattern operator. You may not use

lhunath 1361240549 learn The =~ operator of [[ evaluates the left hand string against the right hand extended regular expression (ERE). After a successful match, BASH_REMATCH can be used to expand matched groups from the pattern. Quoted parts of the regex become literal. To be safe & compatible, put the regex in a parameter and do [[ $string =~ $regex ]]

greycat 1556642755 learn The =~ operator of [[ evaluates the left hand string against the right hand ERE (see <ere>, <regex>). After a successful match, the BASH_REMATCH array contains the matched string and subexpressions (if any). Any quoted characters in the ERE become literal. Best to put the whole ERE in a variable: [[ $string =~ $regex ]]
